Notes:
General Note: Typical values represent the
mean value of all characterization units at
the nominal operating conditions. Typical
drift specifications are determined by
calculating the rate of change of the speci-
fied parameter versus the drift parameter
(at nominal operating conditions) for each
characterization unit, and then averaging
the individual unit rates. The correspond-
ing drift figures are normalized to the
nominal operating conditions and show
how much drift occurs as the particular
drift parameter is varied from its nominal
value, with all other parameters held at
their nominal operating values. Figures
show the mean drift of all characterization
units as a group, as well as the
statistical limits. Note that the typical drift
specifications in the tables below may
differ from the slopes of the mean curves
shown in the corresponding figures.

Consequently, keeping the output
current below 1 mA will ensure the
best offset performance.
